    IR spectroscopy of COmosphere dynamics with the CO first overtone band

    Full text link
    We discuss observations of the weak first overtone CO absorption band near 2300 nm with the U.S. National Solar Observatory Array Camera (NAC), a modern mid-infrared detector. This molecular band provides a thermal diagnostic that forms lower in the atmosphere than the stronger fundamental band near 4600 nm. The observed center-to-limb increase in CO line width qualitatively agrees with the proposed higher temperature shocks or faster plasma motions higher in the COmosphere. The spatial extent of chromospheric shock waves is currently at or below the diffraction limit of the available C0 lines at existing telescopes. Five minute period oscillations in line strength and measured Doppler shifts are consistent with the p-mode excitation of the photospheric gas. We also show recent efforts at direct imaging at 4600 nm. We stress that future large-aperture solar telescopes must be teamed with improved, dynamic mid-infrared instruments, like the NAC, to capitalize on the features that motivate such facilities.Comment: 4 pages, 3 figures, Published in Astronomische Nachrichten on behalf of the 1st EAST-ATST Workshop: "Science with Large Solar Telescopes

    Optimal Pooling in Claims Resolution Facilities

    Get PDF
    The various claims resolution facilities discussed in this symposium exhibit a number of distinctive qualities and governing principles. A common characteristic of many of these facilities, however, is an attempt to avoid the litigation costs of individualized proof of damages by channeling mass tort claims into rough categories for compensation. All claimants within a particular category receive similar compensation, even though they might be able to prove disparate damages through litigation. This article seeks to analyze the efficiency of pooling disparate claims through the categorical compensation of claims facilities. An efficiency standard for evaluating tort law usually focuses on the ability of the legal rules to induce efficient levels of precaution; the costs of implementing the rules are relegated to a second order of importance. But this standard often is inapplicable to claims resolution facilities because many of the settlements that establish the facilities place an absolute cap on the defendant\u27s liability. Ken Feinberg, trustee of the Dalkon Shield Claimants Trust, stressed the importance of such caps to the feasibility of establishing claims facilities: The breakthrough in Agent Orange... and the breakthrough in Dalkon Shield was a court imposed cap on liability. That gives the company total peace .... That is why, once the companies put the money in, they disappeared. Even if aggregate caps are not imposed by judicial fiat, they will be imposed by de facto economic fiat whenever the total liabilities of the defendant corporation exceed its net assets

    Love of Students Is Priority One for Christian Teachers

    Get PDF
    In the Christian university classroom, we too often focus on what we know, and we ignore what we desire. In his book, Desiring the Kingdom: Worship, Worldview, and Cultural Formation, James K.A. Smith asserts that what we desire forms our identity, often superceding what we’ve learned or what we know. Using examples of passion and learning in literature, I will argue that we—as Christian professors and Christian students—can integrate habits into our lives that cultivate a passion for spiritual formation that creates a lifelong and energetic love for learning
